BarBug Straight Up: We all have a responsibility to ourselves and others to be aware that alcohol consumption impairs the senses. There are books and published charts that are intended to act as a guideline for the number of drinks a person of a given body weight may consume per hour and remain under an estimated blood alcohol level. These charts are often available from your department of motor vehicles or police departments. (However, it doesn't take a chart to know that drinking too much alcohol will make you drunk. Drink responsibly.)
